How to send data from overlay to main app about flutter_overlay_window

[xiaojieonly]

Greetings,

I am trying to send data from overlay to main app. My use case is that whe I tap the overlay, I call: await FlutterOverlayWindow("capture");

Then I the initState of the home widget of the main App, I am listening to the overlay listener FlutterOverlayWindow.overlayListener.listen((event) { print("Overlay $event"); });

Unfortunately, the listener (in the main app) is not triggering when I call shareData (from the overlay).

Please help! 😭 TIA

FlutterOverlayWindow.shareData('7hajhsb'); useless too

I meant to type FlutterOverlayWindow.shareData('capture');
Sorry for the typo.

I was able to communicate between overlay and the app using sockets. My Main App creates a socket server and the overlay connects to that socket server.

My use case was that I wanted to invoke a native method by pressing the overlay. So what happens now is that, when I tap the overlay, it send a string over the socket connection and when my main app receives the message, it decides which native method to invoke.

I know this is not a fix, but rather a workaround in case the fix is not coming around any time soon. Hope it helps.

Hello, has this problem been solved? Or if not can someone explain how to communicate between overlay and the app using sockets.

What I want to achieve is that when button on overlay is clicked, then text on my main app has to change.

Amigos pueden usar al comunicación mediante puertos Isolate.

Overlay********
En mi caso uso en overlay los siguiente atributos.

  static const String _kPortName = 'overlay_port';
  final _receivePort = ReceivePort();
  static const String _kPortNameHome = 'home_port';
  SendPort? homePort;

En initiState del overlay registro el puerto con el nombre;

IsolateNameServer.registerPortWithName(_receivePort.sendPort, _kPortName);

_receivePort.listen((message) {
 //Aqui se recibe los mensajes del enviados del home al overlay
  print("message overlay: $message");
});

En el evento onTop() de algun widget del overlay, trato de obtener el puerto del home o main, como ustedes lo usen.

homePort ??= IsolateNameServer.lookupPortByName(_kPortNameHome);

##para enviar mensaje del overlay al home usen, luego de haber registrado su homePort con la linea anterior.

homePort.send("texto"), homePort.send(list), homePort.send( { pro:"prop" } ), etc...

MAIN o Home o como lo usen****

Propiedades del main, o home, o como lo usen.

static const String _kPortName = 'overlay_port';
final _receivePort = ReceivePort();
static const String _kPortNameHome = 'home_port';
SendPort? homePort;

metodo initState

IsolateNameServer.registerPortWithName(_receivePort.sendPort, _kPortName);

_receivePort.listen((message) {
 //Aqui se recibe los mensajes del enviados del overlay al home
  print("message overlay: $message");
});

##para enviar mensaje del home al overlay usen lo siguiente:

overlayPort.send("texto"), overlayPort.send(list), overlayPort.send( { pro:"prop" } ), etc...
